SPECIFICATION forming Part Cf Letters Patent NO. 380,424, datd April 3, 1888.

Application filed Muy 525, 1887. Serial No. 239,345. (No model.)

To @ZZ whom it may concern:

Be it known that I, ItnUBEN CLARKE, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, inventor, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a. specification.

i The objectof the invention is to make a sashfastener which is simple in construction and io when set will hold the sashes firmly closed, and which will also permit the sashes to be opened a few inches for the purpose of ventilation, rendering it impossible to open the window-sashes wider, so as to admit of ingress r 5 to the house from the outside, without iirst closing the sashes and resetting the fastener into such a position that the sash may be thrown up.

Figure l is a perspective view of part of a zo window frame and sashes, partially broken away, showing the portion of my sash-fastener which is let into the window-frame, the catches a and b being in such a position as to permit the sashesto be freely opened. Fig. 2 is a side elevation of part of a window-i`rame, and showing the catches c and Z in such a position as to lock the sashes and hold them closed. Fig. 3 is aside elevation of partof awindow-frame,show ing catches c and Y) in such aposition as to permit of the sashes to be opened for a few inches. Fig. et is a perspective view of the corners of the window-sashes where my sash-fastener is applied, showing the stop-grooves formed in the sashes. Fig. 5 is a detail showing the mechanism which actuates the catches.

Like letters of reference indicate similar parts in the different figures.

In Fig. 1, A is the thumb-piece which passes through the lower sash-Slat, G, into the box II,

4o which covers the mechanism which operates the catches a and b, which work in slots ci and b', formed in said box. This box II is let into a recess formed in the side frames, the strip D being cut through for this purpose, the surface of the box H being flush with sides of grooves in which the sashes slide. B is the'llowcr sash with corner broken away to exhibit my sash-fastener. D is the strip between the sashes B and C, which is usually 5o let into a groove of side frame, and in the line of this strip the catches c and b rest when in position to permit of the sashes being moved freely, as shown in this gure. In this view the flat portion of the thumb piece A is in a horizontal position.

In Fig. 2 the dotted line c shows the position of the top of lower sash, B, and the dot-' ted line d the position of the lower side of the upper sash, C. In this view the sashes are shown locked or closed, the thumb-piece A 6o being slightly turned and the catches a, and b moved slightly away from each other and from the line of strip D, the catch a engaging with the side e yof the socket-plate E in the slot formed in the lower portion thereof, and the catch b in a similar manner engaging with the sides f of the socket-plate F in the slot formed in the upper portion thereof, as fully shown in Fig. 4c. In this view, Fig. 2, the dotted lines indicate the position of the socketplates E 7o and F and of their sides e andf, which butt against the catches a and b, when in the slots formed in said sides and locking the sashes.

In Fig. 3 the dotted lines c and d, marking the top and bottom of the lower and upper sashes, respectively, indicate that the sashes are slightly open for the purpose of ventilation, but not to such an extent as to permit of a person getting through the window. In this view it will be noticed that the thumb-piece 8o A is still more turned and that the catches a and b are still more separated from their original position when the sashes are free to move, as shown in Fig. l. By this extra turn of the thumbpiece A the catch a is caused S5 to pass from the slot formed in the side e and enter the groove in the socket plate E, passing to the top of said groove when the upper sash, C, is opened or let down to the distance permitted by said groove, and the 9o catch b in a similar manner passes the side f in the socket-plate F and enters the groove formed in said socket-plate, running to the bottom thereof when the under sash, B, is raised to the distance permitted by said groove, the catches a and b striking the top and hottom of the respective socket-plates let into the sides of the upper and lower sashes. By referring to Fig. A the foregoing explanation as to the motion of the catches d and b in the roo socket-plates which lock and control the vopening of the sashes, as may be desired, is fully illustrated.

Fig. 4 shows the socket plates E and F placed in position near the corners of the upper and lower sashes, which are recessed to receive them. 2 and 3 indicate the position of the slots through which the catches a and b pass when entering the grooves 7 and 8, formed in the socket-plates -E and F, and also the shoulders at the corners vof the sides e and f, in which the catches a and b engage when the sashes are locked. The dotted lines indicate the position of the box H when let into position in the side frame of the window.

Fig. 5 is a detail, showing the mechanism which operates the catches a and b and which is covered by the box H, which is let into the side of window-frame. I is the end of spindle which is adapted to turn in a bearing formed in the box H and is attached to the thumbpiece A. The squared end of this spindle passes through and is rigidly secured to the notched quadrant-piece K. Lisabar attached to or forming part of the catch b and having a pin, l, formed thereon, which tits into the slot Z', formed in said quadrant, and M is another bar on the opposite side attached to or forming part of the catch a, which is adapted t'o move in the slot a. The slot b, in which the catch b moves, is on the other side and not shown. mis a pin formed on said bar M, which fits into a slot, m,in said quadrant. n n are guides formed in said bars L and M to receive the enlarged head o of the pinO. The end of the head o is beveled off to an edge which fits into the notches 4, 5, and 6, formed in the quadrant, and N is aspiral spring surrounding the pin O and bearing against the enlarged head o and the slotted bearing-piece p. The slot g, formed in this bearing piece p, permits of play for the pin as it is pushed in by the action of the revolving quadrant or thrown in the op posite direction by the action of .the spring N. Vhen the enlarged head o rests in notch 4, the catches a and b are in a position in a line with the strip D, Figs 1, 2, and 3, to permit of the windowr being freely opened Without engaging with the catches. When the head o is moved into the notch 5, the catches a and b are set to lock the sashes, and when the head o is in the notch 6 the catches a and b are moved into such a position in their slots a b as to permit the catches to enter the grooves in the socket-plates E and F and allow cfa partial opening of the window. The window-catch makes a click as the end of the pin O is thrown by the spring N into the notches in the quadrant, which sound will indicate to the person moving the thumbpiece that the catches a and b are in proper position to act. In Fig. 5 the back of the box H has been removed, so as to have the interior exposed. It is of course closed and screwed in position when the window-catch is in place.

From the foregoing description in this specifleation it will be seen that when the windowsashes are partially open, as shown in Fig. 3, it is necessary, in order either to lock the sashes or to throw them freely open, to close them, and then, after the sashes are closed, to reset the catches a and b by means of the thumb-piece A.

What I claim as my invention is- 1. The combination of the box H, having a slot formed therein, the spindle I, the notched quadrant K, the bar L, carrying a catch and a pin which enters a slot formed in said quadrant and having a guide for the enlarged head of the pin O, which is actuated by the movement of said quadrant, and the spring N, which has bearings on said pin and the slotted end of the bearing-piece p, substantially as specified.

2. The combination of the box H, the spindle I, carrying a thumb-piece, the notched quadrant K, the bar L, and the bar M, loosely connected with the said quadrant and adapted Ito move the catches a and b in opposite directions, when actuated by said quadrant, in `Slots formed in said box H,and provided with guides for the head of the pin O, which is so formed as to enter the notches in said quadrant as it is caused to rotate, and the spring N, having suitable bearings and adapted to keep the head of the pin pressed into the notches on the quadrant, substantially as described, and for the purpose speciiied.

3. The combination, with the window frame and sash, a socketplate in a recess in the sash, and a catch fitted to engage a bearing in said plate, of a box let into the side of the windowframe and formed with a slot, a spindleprojecting through said slot, a notched quadrant secured to said spindle, and a bar within said box engaging said quadrant and operated by said spindle to move said catch, substantially as described.
